What else can I help you with?
What factors affect muscle contraction?
the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
What is the mechanical force of muscle contraction is generated by?
The mechanical force of muscle contraction is generated by a sliding of thin filaments past thick ones.
A contraction in which a muscle exerts force lengthens and is overcome by a resistance?
Eccentric contraction (isotonic)
What is the most common form of force muscle production?
The most common form of muscle force production is the concentric contraction force.
What is muscle force and its vector representation?
Muscle force is the force produced by the contraction of a muscle. Force vectors, torque vectors, and difference vectors can all be used to help describe this force.
What is a contraction in which the muscle shorten and work is done?
This is muscle flexion or isotonic contraction.
How does the contraction of the I band contribute to the overall function of skeletal muscle?
The contraction of the I band in skeletal muscle helps to shorten the muscle fibers, allowing for movement and muscle contraction. This contributes to the overall function of skeletal muscle by enabling the muscle to generate force and produce movement.
How does the frequency of stimulation affect the amount of force generated by the muscle?
Increasing the stimulus to an isolated muscle increases the strength of a contraction. A muscle begins to contract when the stimulus is given; however, if the muscle does not finish contracting before the next stimulus hits, then the force of the contraction will increase to finish the contraction. This is known as wave summation.
What is a mucle contraction?
A muscle contraction happens when too much force or stress is forced upon a muscle cavity. Dr. Whitmore PHD
What type of contraction in which the muscle fibers do not shorten are called?
If the muscle can not shorten because the muscle is trying to move a load that is greater than the force, then the contraction is isometric.
What happens to the Z line during muscle contraction?
During muscle contraction, the Z line moves closer together, causing the muscle to shorten and generate force.
What type of muscle contraction will shorten a muscle and decrease the angle between two bones?
Concentric muscle contraction will shorten a muscle and decrease the angle between two bones. This type of contraction involves the muscle generating force as it shortens to move a body part.
